SPECIFICATION forming part of Letters Patent No 300,399, dated June 17, 1884:.

Application filed March 26, liS-l.

To (07] whom it may concern.-

Be it known that we, SOLON R. RUs'r and Anna-run E. Rusr, of Pine Meadow, in the county of Litchfield and State of Connecticut, have invented certain new and useful Improvements in Planes; and we do hereby declare that the following is a full, clear, and exact description thereof, whereby a person skilled in the art can make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon.

Like letters in the figures indicate the same parts.

Figure 1 is a view in longitudinal central section of my improved plane. Fig. 2 is a top view of the same. Fig. 3 is a side view of the same. Fig. 4 is a viewincross-section of the adjust-able yoke on plane denoted by line .1; w of Fig. Fig. 5 is a detail perspective view of the carriage which supports the plane-iron.

Our invention relates to the class of planes having a flexible face and means for adjusting the plane-face for working on a convex or concave surface.

It also embraces certain features ol'.con struclion applicablebroadly to planes.

It consists in the combination of a plane body with a flexible face and means for adjusting the face, and in the combination of devices for holding and adjusting the cuttingiron of the plane-body, as more particularly hereinafter described. v

In the accompanying drawings, the letter a denotes the plane-body as a wholc,1nade of any suitable material-as iron-having a bed, a, through which the plane-iron p1'ojects,vertical sides a, which support the face and the blade adjusting devices, respectively. The flexible face 1: is fast to the plane-basc, and the forked arms 0 and cl are pivoted to the plane-body, as by means of pivots c d, and to the outer ends of the face, as by means of the links 0 andf. Each of these lcvershas a short arm, 6- d, pivotally connected to each, other by rods 1 The yoke 71. is pivoted at its lower end to each arm of the lever 0 near the pivots c, and bears between the upper and lower crossbars, 11 h an adjusting-screw, 1',

(X0 model.)

which is arranged about centrally of the planebody in a. threaded socket in the cross piece 05-, fast to the plane-body in front of the plane-iron. Any vertical movement of 'the yoke imparted to it by the adjusting-screw i is transmitted to the lever c, and by means of connectingrods to the lever d, and from these levers ed to the opposite extremities of the flexible plane-face. This adjustment of the plane-face may be made to a convex surface, as denoted by dotted lines in Fig. 1, or to a concave with equal ease.

The adjustable carriage 7; is snpportcd in the plane-body by means of the longitudinal and central bearings, Z Z, the former resting upon the crossbar a, fast to the plane-body, and the latter in a tubular socket, a", in the plane-body. The carriage 7.: has the downwardprojeeting lugs 7; it, against theinner faces of whichbear the opposite ends of an adjustingscrew, on, which moves in a threaded socket in the crossbar a", fast to the plane-body. This carriage also has the arms a, with the inward-projecting extremities a" so arranged as to grasp the upper surface of the clamp-iron 0, placed ovcr'the iron p upon the carriage, when the parts are in position in the planebody. The lower end of the clamp-iron bears upon the plane-iron just back of the cutting 0, moving in a threaded socket near the upper end of the clamp, and with its point bears upon the upper surface of the plane-iron. The central bearings of the carriage permit of alatcral motion of the carriage and the supported plane-iron, by means of which the pl one-iron may be adjusted to a perfect hearing in the socket in the body. The peculiar method of holdingthe adjusting-screw between the lugs projecting from the carriage prevents backlash or lost motion of the parts and permits a more careful adjustment.

The planc-body, yoke, and the carriage of our improved plane are made, preferably, of mctalas iron-cast to shape, with threaded sockets and bearings for the adjusting-screws and bearings for the carriage formed in subse quent operations.

The main advantage of our improved device is the low cost of its manufacture and simodge, and its upper end bears the clamp-screw plicity of the operating parts, which perform the functions attainable in like devices of the prior art only at considerable expense.

The peculiar method of holding the clamp ing-screw between the lugs on the lower part of the carriage relieves the maker of the tool from exercising any great care to get the bearings for the carriage and the axis for the adjusting-screw parallel, as the opposite ends of the adj Listing-screw may have lateral play between the lugs and not render ihe'dcvice inoperative.

The plane may be quickly changed from a single-iron plane to a double-iron plane by sliding back the clamp and the plane-iron adjusted for, cutting without changing the clamp, but by simply turning the adj listing-screw m.

"We claim as our invention 1. In combination, in al'lexible faceplane, a plane-body, a, a flexible face, I), levers 0d, pivotally connected to the plane-body, to each other by connecting rod g, and to the flexible face-plate, with means for changing the position of said levers and'of the flexible face, all substantially as described.

2. The combination of a plane-body, flexibleface, pivoted levers connecting the said face and the body, a yoke, h, pivotally connected to the said levers, and an adjusting-screw, i, having bearings in the yoke and in the planebody, all substantially as described, and for the purpose set forth.

o. The combination of a plane-body, a, a carriage, it, with the central bearings, Z Z, fitted to suitable bearings in the plane-body, and with lugs 70 k, bearing upon opposite extremities of an adj usting-screw, an, attached to the body, all substantially as described.

4. In a plane, the combination of a planebody, a, a carriage, 7c, with central bearings, Z Z, projecting lugs k 70 and projections w,

an adjusting-screw, m, with its opposite ends bed a, cross-bars a a, and soc et a, the forked levers c d, pivoted'to the body,'connecting rods 9, yoke 71., pivoted to the levers, and adjusting-screw t, with plane-iron p and means for holding the same in the body, all substantially as described, and ,for the purpose set forth.
